  • When Jason Kehl FA’d his ultra-modern v13 test piece, “The New Zero,” in Southern Illinois, it marked a new level for Jason and a new benchmark for technical climbing.

    Inspired by this commitment to pushing boundaries, The New Zero was born. A new performance benchmark for So iLL shoes and for your climbing.

    The New Zero boasts the performance of a sensitive slipper with the stability of a strapped shoe. One of the most soft/high performing shoes in our line. The New Zero performs on steep overhanging bouldering as well as the smallest of smears. Designed for advanced and elite climbers, The New Zero allows for full sensitivity to nuanced footholds and technical bouldering demands.

Best shoes I have ever used! Rubber is super sticky and they fit just like a glove. Great for aggressive bouldering.


These shoes are totally worth the price in every way. They fit like a glove and have the stickiest rubber I have ever used.

Absolutely Amazing

These shoes have seriously helped me step up my climbing (get it!?) The rubber holds tight on all the holds that everyone else is slipping off of. They were comfy on day 1 of climbing, but by day 3, I dont even need a break from them. Both the toe and heel are covered really well in rubber, so I've been able to improve both my toe hooks and heel hooks. I wear a 7 street shoe (women's), and I ended up with the 7.5. My toes are nice and curled in there, but if I wanted to be more aggressive I probably could have handled a 7 after they got broken in (which was by like day 3, as I said above.) That being said, I am super happy with the 7.5! I am going to buy my fiance a pair for Christmas! On top of all the above stated benefits, they're so snazzy! I get at least one compliment on them every time I climb at the gym

Strong, supportive, comfortable, and high performance

This shoe has been great so far! I've had 2 really full on sessions with them so far and they've done really well. At first I though I may have ordered too small of a size, but the second session felt way more comfortable.

Can’t say enough good....

I’ve been climbing for a few months now. I started with a pair of the streets and liked them from the minute I put them on. When it was time to get another pair (wore out my streets) I shopped around. A lot! I’ve have worn so many different brands that have been recommended to me by various people for various reasons. Everyone seems to know what’s best for me more than I do! Lol some were good, some not so good. Then a friend of mine recommended I try the New Zeros. They are a bit pricier than some other brands so I was skeptical. Are they that much better? I had a great week at work so I took a chance. I could not be happier with my purchase. These shoes felt like they were built specifically for me. Other shoes feel like, well, shoes. I get hot spots and they just don’t feel super precise. Not with the New Zeros. These feel like they are painted on. Like socks. They are a part of me when I’m on the wall. I’m usually into harder soles but these have made me a believer in the soft shoe category. I’m now sending better than I ever have and more importantly I now trust my feet in situations I didn’t trust them in just a few weeks back. So ILL has outdone themselves with these shoes. I’m now about to sell of all of my other shoes because I simply don’t need them. I also bought a pair of Free Range pros to have a harder pair for edging and overhang climbing. Again, they fit perfectly. So ILL blends performance, comfort and aesthetics into the perfect package. I didn’t know climbing shoes could be this comfortable and I cannot wait for the Nee Zero Pro’s to come out. Provided they keep producing these 3 models (other brands like 5.10 discontinue every shoe a year after release. Bad job IMO) So ILL will have a customer for life in me. Thank you guys so much for making a product that so much better than I could ever have hoped For.

Perfectly Soft

The synthetic vegan upper fits like a slipper, and the fabric is normally used on the inside of durable work boots in the footwear industry. For a shoe at this level, it is incredibly comfortable. The thread we use for the upper is specially made in the southeast as one of the softest threads in the world, and cannot be felt in the toe box. This shoe is sensitive and every detail matters when performing at a high level.

No Hot Spots

Dark Matter toe rubber meets the rand by butting up together, with no overlapping. This is incredibly hard to do in production and provides no hot spots.

The New Zero is coated in "Dark Matter" rubber, part of the "UnParallel Rubber" family, a sticky outsole rubber originally formulated for the United States Navy Seals to ensure security in foot placement during approaches. It's the stickiest rubber you will experience.
